What is the equation of the graph below?
Harlamova29_29 [7]

Hey there! :)

Answer:

y= cos (x+ \pi })

Step-by-step explanation:

Normally, in the parent function y = cos x, when X = π, Y = -1. However, in this graph, when X = 0π, Y = -1.

Therefore, there has been a horizontal shift of π to the left. The new equation would be:

y= cos (x+ \pi })

Calculate cos theta to two decimal places
Ghella [55]

Answer:

B. 0.72

Step-by-step explanation:

In order to find the answer we need to use the following formula:

a^2=b^2+c^2-2bc*cos(\theta) where:

a, b, c are the length of the sides and \theta the angle, so:

7^2=10^2+8^2-(2*10*8)*cos(\theta)

49=164-(160)*cos(\theta)

cos(\theta)=0.71875

In conclusion, cos(\theta)=0.72, so the answer is B.
